Dear Bill, Please accept my congratulations for all your hard work in developing the SEXPR domain. This seems to lead to a complete system for manipulating and simplifying symbolic expressions within fricas, including trigonometric functions, etc.
I wanted to inquire about the following. (1) I hope that the SEXPR domain will be included in the next version of fricas. (2) Is there a debian package for fricas that can be conveniently installed with the synaptic package manager in ubuntu based linux? (3) Given a matrix in fricas with symbolic entries of type SEXPR. Will fricas automatically re-generate all the built-in fricas linear algebra functions like nullspace, determinant, etc for this type of matrix? (4) Is the above possible for other built-in fricas functions?

See the experimental code here: http://axiom-wiki.newsynthesis.org/SandBoxSymbolicExpressions A simple computation using patterns in trigonometric symbolic expressions as discussed on another recent email chain on this list is shown in http://axiom-wiki.newsynthesis.org/SandBoxSymbolicTrig There is more testing and considerably more work to do before I would consider this complete. And of course I need to spend some time on documentation for which your comments and questions would be invaluable. I would be very happy to receive criticisms, comments and suggestions. -- You received this message because you are subscribed to the Google Groups "FriCAS - computer algebra system" group.
